With the Cenotaphs in game, Master resource processing forms are available for Stone, Metal, Wood, Essence. 3 of which a Dragon could theoretically use.
I was able to hit 1202 Stoneworking, with the help of biped buffs
level 100 adventurer (needed for base str and training points)
level 100 crafter
approximately 2/3 of of the max training points that can be put into Strength, put into strength.
strength scales teched with stoneworking
strength scales teching with smelting
For myself, those were originally 2 different sets. To be able to hit 1200 in both, I had to make new chest and forelegs, teched with armor socket, smelting, stoneworking. three level 60 strength crystals were placed in the sockets (+135 strength)
Triple socketed claw with level 60 strength, dexterity, power crystals
Use Determination
Self buff with Promote Vitality 5
Tier 5 bolster potions: Strength, Dexterity, Power (I also used a focus, but do not think it helped)
Tier 5 gifts: Strength, Power, Dexterity, Focus
Tier 5 enhances: Strength, Power
Tier 5 surge: Strength
Silken Banner of the volcano: (+60 to +85 strength)
The longer lasting buffs can get ahead of time, but the surge only lasts 2 or 3 minutes. Need someone close to the Cenotaph to Cast that on you, then use the banner (Requires a flame bone splinter)
You have about a 2 minute window to greet Gaarius (think thats correct spelling), get the form, and scribe it.
Smelting doesn't need the banner to hit 1200, just all the regular buffs, potions, and the surge.
From all the effort it takes to get there, it's not realistic for Dragons to work T6 Stone and Metal until those craft processing quests are added to the game. Those are the only 2 that are not yet added.
Essence, Gemworking can hit 1200 without the surges, potions, and banner.
